STAMP-PAD.

Specification of Letters Patent.

Patented Apr. 23, 1912.

App1ication filed January 14, 1911. Serial No. 602,571.

To all whom it may concern Be it known that I, HARRY S. FOLGER, a citizen of the United States of America, and a resident of Chicago, county of Cook, State of Illinois, have invented certain new and useful Improvements in Stamp-Pads, of which the following is a specification.

My invention relates to stamp pads and has for its object improvements in such devices.

In the accompanying drawings, Figure 1 is a plan; Fig. 2 is a section on line 2-2 of Fig. 1; Fig. 3 is a section on line 3 8 of Fig. 1; and Fig. 4c is a plan of the grooved plate and ink reservoir attached thereto.

In the said drawings A is a metal plate having a bead A formed thereon near the edge and a series of inclined grooves A within the pad inclosed by the bead A The grooves A are deeper at that part of plate shown in the lower part of the drawing and gradually taper 0E into Very shallow grooves near the upper edge. The said upper edge of the plate A is bent up to form a tube B, the ends of which are inclosed by caps B which may be removed. There is an opening in the tube B adjacent to the plate A and between the beads A This opening will be seen in Fig. 3.

Resting on the top of the plate A and inside of the pad bounded by the bead A is a wick C, one end of which extends through the opening into the tube B and is coiled therein as shown in Fig. 3. Resting on top of the wick O is a pad of absorbent material of the ordinary kind which consists of a series of layers and is designated by the character D.

The plate A rests upon a wooden block E. A metal frame F surrounds three sides of the wooden block and at its upper edge has an inwardly or downwardly curved lip F which is adapted to engage the outer edges of the pad where certain parts of the pad or layers thereof extend over and beyond bead A This frame is pressed downwardly on to the pad so as to clamp the pad around the bead, and is then secured in place by small nails G driven through holes in the frame F and into the wood E. In this way the pad D and plate A are secured in position by a clamping action. Pivoted on the frame F at a point H is a cover J which is intended to inclose the pad and protect it from dirt and dust when not in use.

To use the pad one of the caps B is removed and ink is inserted in the tube B where it comes in contact with the coiled inside end of the wick C. By capillarity the wick O conveys the ink underneath the pad from which it is absorbed and distributes it through the absorbent material thereon. It will be noticed that the reservoir B is somewhat higher than the pad itself, and particularly higher than the wick. The result is that there is a tendency for the ink to flow by gravity under the pad. The wick prevents this ink from flowing fully and completely and acts as a cover for conveying it through capillary action. To a certain extent however, the ink flows down through the grooves A under the wick but does not flow beyond the deepest part of these grooves shown at A These grooves are in the nature of a secondary reservoir as they will hold a small amount of ink if there is more than the wick and pad will conveniently absorb. When the reservoir B is empty, it may be filled again by removing one of the caps B and then replacing the same.

What I claim is:

1. In a self-inking stamp pad, a base, an ink holding device located along the rear edge thereof and of greater length than the base having caps for inclosing the ends, a wick located within the ink-holder and eX- tending therefrom, a plate having a series of inclined grooves, terial, a clip for holding the pad in position, and a cover for said pad.

2. In a stamp pad, a base, a metal plate thereon having a series of parallel inclined grooves, said grooves being widest and deepest at their outer ends, a cylindrical reservoir located at the inner end of said metal plate, caps for closing the ends of said reservoir, an opening in the reservoir, a wick partly within said reservoir and extending therefrom through the opening and a pad of inking mat Z l across the face of the plate, a pad of aband a cover pivoted to the frame for insorbent material located above and resting closing the pad. 10 on that portion of the Wick lying on the Signed at Chicago this 11th day of Janumetal plate, a metal frame surrounding the ary 1911.

base and secured thereto, having its upper HARRY S. FOLGER. edge bent inwardly and downwardly to form a clip for holding the upper layers of the pad material and the covering therefor,
